California's rivers and reservoirs, one at a time.

A page for each of California's major rivers, reservoirs and natural lakes: how much water a reservoir holds today against its capacity and its average for the date, how its storage has moved through every water year since 1995, which districts draw on it, and the rivers, agencies and counties around it.

Reservoir pages carry the state's daily storage record. River pages link each river to the reservoirs on it, the streams that feed it and the districts with water rights along it. Every district page links back here from its water sources.
